Forge app `asApp` requests fail when IP allowlist is enabled.

Issue Summary

When using apps (add-ons) developed with Forge, the apps making asApp() requests may not work as expected if the user has IP Allowlisting enabled. The list of allowed IP addresses are listed in https://support.atlassian.com/organization-administration/docs/ip-addresses-and-domains-for-atlassian-cloud-products/#Outgoing-Connections and the announcement was documented in

  Important

  If you plan to use these IP address ranges, it’s important that you monitor Atlassian’s documentation for changes to this range. A JSON file containing this information is published to https://ip-ranges.atlassian.com/, which may aid automation.

Steps to Reproduce

1. Create/ install an app built with Forge;
2. Try to use the app on a site where IPAllowlisting is enabled;

Any asApp() requests will be blocked by IP Allowlisting.

Expected Results

The app should work without problems.

Actual Results

App using asApp() requests, throw an error and the app doesn't work at all.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
